CICS Storage Accounting Area (SAA) overlay assistance
Fault Analyzer provides two features designed to assist with CICS® SAA (Storage Accounting Area) overlays:
- Concurrent CICS® task
storage information
A display is available from the interactive reanalysis report, which cannot only be used to identify overlays in the current transaction's storage, but also includes relevant storage areas owned by other transactions which might have been involved in the overlay.
For details, see CICS Transaction Storage Summary.
- Early detection of SAA overlay by implementing an XEIIN global user exit
The XEIIN exit is used to ensure that if a storage overlay is detected by CICS®, that either Fault Analyzer is invoked to perform normal real-time analysis, or an SVC dump is taken which can later be reanalyzed.
For details, see Implementing an XEIIN global user exit.
